Pai and Poony are really nice hosts. We were warmly welcomed when we arrived despite the late hour (~8PM). They have always been there when we had questions and gave us good advice.
The apartment was really great: private bathroom, hot water, comfortable bed, AC, small balcony... There is no facility to cook but it is not a problem as guests have access to a microwave in the common parts. The apartment was very clean and well-designed.
It is a bit far from the centre of Bangkok, however the ARL line is close which provides an easy access. There are many convenient stores (one of which is 24/7) and fast foods near the place.
The complementary washing service was exceptional. Tony (the housekeeper) was really nice and lovely.
We warmly recommend this place.
